I have two ideas for food-related apps.
1. Food Dictionary: I often run into situations where I don’t understand a good portion of the menu/ingredients at restaurants. So I’m interested in making a food dictionary app that can be helpful in such situations. The app will contain general information + images of various cuisines from around the world and their commonly used ingredients. In short, this app will be a visual dictionary specifically for food, and I think it could be particularly useful when traveling abroad.
2. Gummy Bear Weather: A weather app with a gummy bear theme… Perhaps this will make any sort of weather feel nicer? In this app, whether it is snowy, rainy, sunny, etc., everything will be represented through gummy bear imageries. This app isn’t exactly meant to solve specific design issues, but rather, is purely for fun.
I’d suggest going with the food dictionary. I think there will be more to explore there than in the gummy bear weather.
It could be good to limit the audience somewhat, so perhaps just with two languages or countries. Do you imagine that it’s an app for studying up before you travel or one for using while you’re in the field? I think that will affect things.
